如何设置 apache 以提供无错误页面内容？我不想要默认行为、空白或自定义页面。除了标题，我不想返回任何内容，所有浏览器都必须显示自己的本机错误页面。我正在使用 Apache 2.2.22
我想使用 强制日志文件轮换logrotate -f /var/log/syslog，但它只是返回音调：
error: syslog:1 unknown option 'May' -- ignoring line
error: syslog:1 unexpected text
我知道在这个系统上 rsyslogd 正在运行。如何旋转/var/log/syslog？我想要它是空的。
我已经在 debian squeeze 上安装了 bind9。这是我的named.conf.local文件：
options {
directory "/var/cache/bind";
auth-nxdomain no;
listen-on { any; };
listen-on-v6 { any; };
};
zone "devhub.pl" IN {
type master;
file "db.devhub";
};
这是我的区域文件：
$TTL 3h
devhub.pl. IN SOA ns1.devhub.pl. root.devhub.pl. (
2012051201 ; serial
3h ; refresh
1h ; retry
1w ; expire
1h ) ; negative caching
IN NS ns1.devhub.pl.
IN NS ns2.devhub.pl.
ns1.devhub.pl. IN A 193.93.207.231
ns2.devhub.pl. IN A 193.93.207.231
www IN CNAME devhub.pl.
named-checkconf并named-checkzone报告一切正常，但是当我尝试将外部 DNS 设置为
ns1.devhub.pl -> 193.93.207.231
ns2.devhub.pl -> 193.93.207.231
我的提供商的管理面板显示如下错误：
dns1: ns1.devhub.pl server isn't configured for devhub.pl domain. Please contact admin...
dns2: ns2.devhub.pl server isn't configured for devhub.pl domain. Please contact admin...
我缺少什么？有什么建议么？

这个怎么样address in use——有问题吗？
顺便说一句，绑定已 chroot 并正在运行/etc/init.d/bind9 start，然后/etc/init.d/bind9 status说could not access PID file for bind9 ... failed!
我想将我的来宾系统固定到现有网络 - 他们必须像主机一样从同一个 dhcp 服务器获取 ip，并且可以通过该网络与主机和其他服务器通信。我可以这样做吗？怎么做？
